Whether it be a thrift shop, a liquidation store, flea market, garage sale, or at school, I would like to know what places other than a supermarket or Lego store that you have found Bionicle sets (intact or wrecked).
I found whole lots of Bionicle sets and parts at Value Village (thrift store) a few months ago. Every few weeks I would go there and there would be a new bag of parts (somebody in my area must've been a heavy collector and decided to donate them all away). But now, there are no more.
At school I found a bunch of Mctoran and metrutoran in a box labled "stop-motion figures" locked away in a cabinet in the tech room. There was also a box of assorted parts that I found in my school's "play-room".
